Back board for WE phones

[Vern P]

WE made wood back board for the 354 and 554, to help hold the telephone to the wall.  The one for the 354 is #172 "A", this has round corners, and was made in Black and Ivory. 

The one for the 554 is #172 "B", this has square corners, and was made in the early colors.

I am looking for these in Ivory, Yellow, Dk. Gray and Dk. Blue.

When the new light colors came out in 1959, they changed to back board to plastic, these are #172 "C". They were made in all the colors the 554 was made in at that time.  I am looking for a Lt.Blue in this type.

When the Turquoise was added in 1964, the Turquoise back boad was added.

There is also 183"B" and 191"C" but I don't know the date or other info on these.
